Molecular Structure and Acid Strength

Postby ZoeHahn1J » Wed Dec 06, 2017 10:02 pm

What are the factors in determining acid strength? How can we identify one acid as being stronger than another using periodic table trends?
Thank you!

Acids tend to be stronger with higher bond polarity (when comparing acids with central atom elements in the same period) and with weaker bond strength (when comparing acids with central atom elements in the same group). Oxoacids are stronger if the central atom element is more electronegative and if there are more oxygen atoms bonded to the central atom.

Thanks so much!
Also, would someone be willing to explain why across a period, a stronger bond = stronger acid, but down a group, stronger bond = weaker acid? I'm a little confused. Thanks again!
